Eleven years ago today, George Harrison died at the age of 58 in Los Angeles.

And exactly one year after that some of the late Beatle's closest friends -- including Eric Clapton, Jeff Lynne, Tom Petty and Harrison's surviving bandmates -- gathered for an all-star tribute at London's Royal Albert Hall.

To mark the 10th anniversary of the "Concert for George," YouTube is streaming David Leland's documentary on the event for 24 hours. (Watch it below.)

Highlights from the film -- which intersperses performances from the concert with interviews and bits of rehearsal footage -- include Paul McCartney's ukulele-fied "Something," Clapton's hard-edged "While My Guitar Gently Weeps" and a scorching rendition of "Isn't It a Pity" by Billy Preston.

And then there's Ringo Starr bopping his way through "Honey, Don't" (by Harrison's beloved Carl Perkins), while Lynne plays guitar and wears a very small hat.
